Brake pads

A typical vehicle braking system consists of a pair of brake pads, a brake disc and a brake calliper for each wheel.

The pads are fitted in the calliper with their friction material almost touching the two sides of the brake disc.

When the brake pedal is pressed, hydraulic fluid in the calliper pushes each restriction pad against each side of the rotating brake disc. This results in friction which slows down and eventually stops the vehicle.

When yous recollect of the number of times this simple activity takes place every day, calendar week, month and yr – it'due south no surprise that brake pads endure gradual wear, so they need replacing regularly.

How long do brake pads terminal?

The weight of your car

Another factor in brake pad wear is the weight regularly being carried past the vehicle, e.one thousand. 4 or five passengers, fully loaded kicking, towing a caravan etc. When the vehicle is lighter it's easier to slow down and stop with less braking effort required.

A vehicle used by a 5-person family is obviously heavier than say, 1 used by a couple – so stopping it in the aforementioned amount of fourth dimension requires greater pressure and puts more strain on brake pads.

Blazon of brake pads

The type of pads you can have in your vehicle also vary in durability:

• Organic brake pads are by and large the cheapest but take a shorter life span
• Low metal brake pads can be noisy, but have a slightly longer life expectancy than organic
• Semi-metallic or sintered brake pads utilise fused metal particles such as copper and statuary along with other materials. Although they offer excellent braking performance and have a long life expectancy they may wear brake discs down quicker than other pads
• Ceramic brake pads last longer than other materials and are more resistant to wear. The drawback is that these are also more expensive than others

How many miles you comprehend
